APPARATUS FORMAKING AND STORING OXYGEN.

SPECIFICATION forming part of Letters Patent No. 653,261, dated July 10, l1900.

Application iiled March 3l, 1899. Serial No. 711,251. (No model.)

To a/ZZ whom it may concern:

Be it known that we,WILL1E RILEY, residing at Godwin street, Bradford, and ABRAM KERSHAW, residing at Dorrington street, Leeds, England, subjects of the Queen of England, have invented certain new and useful Improvements in Portable Oxygen Generators and Holders, of which the following is a specification.

This invention relates to improvements in portable oxygen generators and holders; and its object is to provide a generator that is automatically regulated by the holder.

In the accompanying drawings, Figure l represents an elevation of our improved apparatus. Fig. 2 is a plan view of the generator and the mechanism for moving the lamp. Fig. 3 is a longitudinal section, and Fig. 4 is a cross-section, of the same. Fig. 5 is a separate cross-section of the generator, and Fig. 6 is a plan view of the same. Fig. 7 is an enlarged detail vi-ew of the pawl mechanism shown in Fig. 2.

The generator A is charged with a number of cartridges or cylindrical blocks of oxygen -mixture, which when heated evolve oxygen,

and these blocks are held a suitable distance apart in any convenient manner. The generator is supported upon the standards A2, hinged to the bottom A3 of the box or case A", so that they can be turned down against the bottom when not in use. The generator is connected to the gas-washing vessel B by the iexible tube A?.

The gasholder consists of two cylinders C and C2, the latter of which when the holder is empty lies within the other. Both cylinders are completely closed at the bottom, and the sides of O2 are connected at Ca to the top of C by the annular flexible india-rubber connection C4. This connection allows the cylinder C2 to rise and fall in the cylinder C within the limits allowed bysuch connection. The broken lines, Fig. 5, represent the holder full of gas. The washing vessel B is preferably placed in the cylinder O2 and is connected to the holder by the flexible tubeV B2. The liexible service-pipe A connects the holder with the burner.

The lamp D is mounted upon the carriage D2, sliding upon the guides D3 and D4, and the pawls D5 and DI3 are pivoted to the under side of the carriage upon the pins D7 and D8. A

spiral springD9,stretched between projections E and E2 upon the pawls, keeps the pawl D5 pressed against the slide F,made with notches F2, and the pawl D6 against the inner edge of the guide D3, made with notches E3. A knob E4 is fixed to the pawl D5, by which it can be moved to disengage it from the notches F2, and this pawl is provided with a heelpiece E5, which when moved in this way engages the projection E(i on the pawl D6 and also disengages the latter from the notches E3, leaving the carriage free to be moved from one end to the other of the guides D2 and D4.

' When the cylinder C3 rises,the bridge-piece O6 across the top engages the antifrictionroller H, pivoted at the junction of the togglelevers H2 and H3. The other end of the lever H2 is pivoted to the under side of the bottom A3 of the box A4, and the lever l-I3 is pivoted to a projection H4 on the under side of slide F, projecting through a slot Hin the bottom A2. The cylinder O2 continuing its upward movement lifts the toggle-levers H2 and H2, this moving the slide F in the direction of the arrow, Fig 3. As the cylinder O descends the spring G, stretched between the pin G2 in the bottom A3 of the box and the projection H4 on the slide F, pulls the slide in the opposite direction to that in which the said arrow is pointing, and one of the notches E engages the pawl D5 and draws the carriage along with it a sufcient distance to carry the lamp beneath the next cartridge in the generator. This is repeated each time the cylinder C2 rises.

We claim-n 1. The combination with the toggle-levers H2 and H3, of the slide F, the lamp-carriage D2, means for engaging the slide and lampcarriage substantially as herein shown and described.

2. The combination with the toggle-levers H2 and H3, of the slide F and the lamp-car-l riage D2 fitted with the pawls D5 and D6 substantially as herein shown and described.

In witness whereof we have hereunto set our hands in presence of two witnesses` WILLIE RILEY. ABRAM KERSHAW.

Fig. 7 is a plan view, on a larger scale, of the v carriage and certain other parts.
